Sex Linked Diseases

Sex-linked diseases are passed down through families through one of the X or Y chromosomes. The term "sex-linked recessive" most often refers to X-linked recessive. Diseases such as hemophilia and Duchenne muscular dystrophy occur from a recessive gene on the X chromosome. Sex-linked traits are genetic characteristics determined by genes located on sex chromosomes. Like traits that originate from genes on autosomes (non-sex chromosomes), sex-linked traits are passed from parents to offspring through sexual reproduction. Genes that are found on sex.

SEX LINKED DEFINITION

Sex-linked definition, (of a gene) located in a sex chromosome. See more. Sex linked genes are genes that are in the sex chromosomes and that are therefore inherited differently between males and females. Common examples of sex linked genes are those that code for colorblindness or those that code for hemophilia (inability to make blood clots) in humans.
